Constructors

Collectors()

Default constructor: even if the corresponding Java class does not have one, it is mandatory for JCOBridge

public Collectors()

Collectors(params object[])

Generic constructor: it is useful for JCOBridge when there is a derived class which needs to pass arguments to the highest JVMBridgeBase class

public Collectors(params object[] args)

Parameters

args object[]

Properties

BridgeClassName

Java class name to be instantiated

public override string BridgeClassName { get; }

Property Value

string

IsBridgeAbstract

true if the BridgeClassName is an abstract class, i.e. cannot be created an instance

public override bool IsBridgeAbstract { get; }

Property Value

bool

IsBridgeCloseable

true if the BridgeClassName implements Closeable

public override bool IsBridgeCloseable { get; }

Property Value

bool

IsBridgeInterface

true if the BridgeClassName is an interface, i.e. does not have any public constructor

public override bool IsBridgeInterface { get; }

Property Value

bool

IsBridgeStatic

true if the BridgeClassName is a static class, i.e. does not have any public constructor

public override bool IsBridgeStatic { get; }

Property Value

bool
